Brooker Creek Headwaters Nature Preserve

Image
Brooker Creek is a small waterway in Northwest Hillsborough and Pinellas Counties. Brooker Creek flows through two nature preserves, agricultural, and residential areas before eventually emptying into Lake Tarpon. Lake Tarpon then flows into Tampa Bay. Brooker Creek Headwaters Nature Preserve is a 1121 acre preserve located in the Keystone area of Hillsborough County. It is owned by the Southwest Florida Water Management District and operated by Hillsborough County Conservation and Environmental Lands Management Department . This preserve exists to protect the health of the headwaters of Brooker Creek and its contribution to Lake Tarpon and Lake Keystone. The preserve includes several miles on unpaved hiking paths and also contains portions of the paved Upper Tampa Bay Trail from Van Dyke Road to the Suncoast Parkway on Lutz Lake Fern Road. The headwaters consist of a chain of wetlands on the north side of Lutz Lake Fern Road (outside of the preserve boundary) and flow southwest until...

Fix Cisco ISE Messaging Service

Cisco Identity Services Engine 2.6 introduced the concept of the ISE Messaging Service as an encrypted, lightweight protocol to replace syslog communication between the ISE nodes for logging purposes.  The ISE Messaging Services runs over TCP/8671.  In 2.6 Patch 2 and later, the Cisco ISE Messaging Service is enabled by default.   The overall implementation of the ISE Messaging Service has been buggy (but has gotten much better in recent versions) in both new ISE builds and upgrades.  One solution is simply to disable the ISE Messaging Service within Administration > System > Logging.  But then the ISE logging traffic isn't encrypted and the legacy syslog delivery method is not as efficient as the ISE Messaging Service so we will focus the rest of this article on how to identity and fix the ISE Messaging Service. Problem Identification Usually problems with the ISE Messaging Service involve a blank Live Logs page.  You know authentication is...

ClearPass MPSK per Device Type with Profiling

Image
Multiple Pre-Shared Key or MPSK helps solve for IOT or other endpoint device types that are not 802.1X capable.  The Aruba ClearPass default implementation of MPSK (the configuration created by the wizard) requires manually registering, enrolling, and managing individual PSK keys per endpoint using the ClearPass Guest dashboard.  While the most secure approach, excluding any sort of API based automation, this can obviously be a nightmare to manage and support due to the sheer number of PSKs.  This approach instead delivers a unique PSK per device type (printer, thermostat, etc.) so that each flavor of endpoint would have its own PSK.  If one PSK was compromised, then only those endpoints would need to be manually re-configured.  PSK rotation would also be limited to only those specific device types allowing rotation to take place slowly over several weeks rather than all devices at the same time on the SSID with a traditional single PSK; lessoning the burde...
